C U R BST O N E SPECIFICATION forming part of Letters Iatent No. 428,007, dated May 13, 1890.

Application filed November 6, 1889. Serial No. 329,400. (No model.) I

To all whom it may concern:

Be it known that I, IsRAEL L. LANDIs, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements*A in Curbstones, of which the following is a specification, reference being had therein-to the accompanying drawings, in which- Figure l represents a sectional view ot` a curb and the adjacent sidewalk and gutter; Fig, 2, a horizontal sectional view ot the two adjacent ends ot two curbstones; and Figs. 3, et, 5, U, and 7, views similar to Fig. 1, showing modifications of the securing devices, which will be fully hereinafter set forth.

It is a well-known fact that the main difficulty or drawback to the employment of stone curbs for sidewalks arises from the fact that a comparatively short time after they have been set they settle into the earth and tilt one way or the other, some stones settling and tilting more than others, thereby throwing them out of alignment with each other and presenting an irregular and unsightly appearance, as well as bei n g dangerous to pedestrians.

It is the object of the present invention to ohviate the above drawback by keeping the adjacent ends of the stones in line with each other and preventing them from settling or tilting one way or the other, as will presently appear.

In the drawings annexed, a designates the curbstones, which may be of the ordinary construction and dimensions and set in the ground in the usual manner, their upper edges being flush with the pavement. The adjacent ends ot' the curbs are correspondingly drilled or bored for the reception'of a connecting pin or bar l), the ends of the stones setting close to each other, as shown. Connected to this pin l) is au anchor-rod c, which extends back into the earth under the sidewalk, and is hooked over an anchor-block or closely together. The pins Z1 maybe more securely fastened in their recesses, if desired, by cement or other plastic compound.

The anchor-rod c, as shown in Figs. 3 and 4, may assist in supporting the sidewalk, it desired. l

Extending across the joints of the curbs,

-at their rear sides, are bars d, provided with projections d at their ends, which enter recesses in the stones, these bars being provided with holes about midway their length for the passage of the anchor-rods. These bars will prevent spreading apart of the curbs and assist in holding them in alignment.

In order toY further support the curbs (especially long curbs) and relieve the pins somewhat, I may. attach a supplemental anchor-rod b', as shown at lower end of Fig. 2, to the back of the stone at anysuitable point between its ends, this rod being attached to the stone by means of a wedge b, Jformed on its end, and a loop 11'", dovetailed into the stone by means of a small wedge 7s.

Various devices may be employed to connect the anchor-rods to the connecting-pins and the plates d without departing` from the invention in the least. I have shown a few ot' these modifications, and will now describe them.

In Fig. 3 the anchor-rod is provided with a slotted bent portion c, which is clamped to the bar d by an eyebolt c and clamping-nut e, the eye of the bolt being secured to the pin b, as shown.

In Fig. 4; the anchor-rod c is provided with a downward extension f, which is adjustably but. rigidly clamped to the bar (l by means of a wedge f and a slotted eyebolt f, as shown.

In Fig. 5 the bar d is omitted, and a wedge g is formed on the anchor-rod and passed through a slot in an eyebolt g, whereby the parts are rigidly secured together.

In Fig. U the anchor-rod is omitted and the eyebolt c clamped to the bar d by its nut e.

Any of these modifications may be employed Without departing from the invention, and many others may be devised by a skilled mechanic. I therefore do not wish to contine myselfto the specific construction shown and described.

It will he observed that by my invention it IOO will be impossible for the stones to settle or tilt independently of each other.

As shown in Fig. 5 the rods c may be enlbedded in the sidewalk when the salue is constructed of any n1aterial laid while in a plastic state-such as concrete, cement, artitcial stone, &e.

By forming the connectingbar Z1 rectangu lar in shape, as shown in Fig. 7, the curbs will be further prevented l'roln tilting or twisting independently ot each other. When rectangular bars l) are used, the bars c may he provided with a head and passed through the said bars l1, as shown in this figure, or they may be hooked over the bars, as shown in dotted lines.

Having thus described my in vention,what I elahn isl. The combination, with two adjacentcurb stones provided with recesses, of a har d, extending across the joint between the ends of the two stones and provided with hooks or extensions d', which enter the recesses in the said stones, whereby the stones will be etfectually prevented from parting, substantially as described.

2. The combination, with two adjacent en rbstones having formed in their adjacent ends longitudinal recesses, of a bar connectingl these curbstones and setting in the said longitudinal recesses in the sfunc, and an anchorrod connected to the said bar and extending back between the adjacent ends of the stones and into the earth beneath the sidewalk, substantially as described.

3, The combination of a curb, a loop if",

dovetailed into the curb, and an anchoriilgrod connected to this loop and extending back into the earth under the sidewalk, substantially as described.

L The combination, with two curbstones having their adjacent ends provided with corresponding longitudinal recesses, of a bar setting in these recesses and connecting the stones together, so as to keep them in alignnient, a bolt or rod c, connected to the said bar and extending rearward between the ad jacent ends of the stones, a bar d, provided with projections d', which enter recesses in the rear faces of; the saidcurbstones, and means for clampin the bar d te the back of the cnrbstoncs and to the bolt c, substantialI3v as described.

5. The combination, with two enrbstoncs correspondiugly recessed in their adjacent ends, ot.' a bar setting in these recesses and serving to keep the curbstoncs in alignment, a holt; e, connected to the said bar and extending rearwardly between the aifljacent ends ol' the stones, the said ends being recessed for the reception of the bolt, a bar d, clamped to the back of' cnrhstones and to the projecting end of the bolt c, and an anchoringrod connected to the bar d and bolt e and extending back under the sidewalk, s11l1stantially as described.

ln testimony whereof Iaffix my signature in presence oi' two witnesses.
